This week on Public Health Out Loud, co-hosts Dr. Jim McDonald and Dr. Philip Chan talk about the health effects of PFAS (per-and polyfluoroalkyl substances), a group of chemicals that have been used since the 1940s to make products water-, grease-, and stain-resistant.  

According to the Environmental Protection Agency, PFAS can be found in the blood of people and animals all over the world. And scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects, like increased cholesterol levels or developmental and growth delays in children. 

Our guest expert this week is Dr. Joseph Braun. He’s an environmental epidemiologist and a professor at the Brown University School of Public Health. Why are PFAS called “forever chemicals?” What can people do to reduce their risk of exposure to harmful chemicals? Download this week’s episode to find out.
